Listening to: This Is London - Don McGlashan

IBM developerWorks has a very useful article describing how to extend RSS using namespaces.

With great use, come a lot of headaches. Some developers complain that they need to shoehorn concepts in items and that the latter are too restrictive. To address the limitation, RSS 2.0 is designed as an extensible language. The principle is simple: the RSS elements themselves are not included in a namespace (for backward compatibility with RSS 0.92), but developers are free to extend RSS by adding elements in a namespace of their own.

When a tag has a namespace, RSS readers should try to recognize the extension from its namespace. If they succeed, then they can process the elements. If they don’t, they should simply ignore the elements.
